RAIL AND RAIL-CHAIR FOR GlRDER-RAILS.

SPECIFICATION forming part of Letters Patent No. 391,553, dated October 23, 1888.

Application filed February 15, 1888. Serial No. 264,084. (No model.)

To all whom, it may concern:

Be it known that I, ARTHUR J. MOXHAM, of Johnstown, in the county of Cambria and State of Pennsylvania, have invented a new and useful Rail and Rail-Ohair for Girder- Rails, which invention is fully set forth and illustrated in the following specification and accompanying drawings.

The object of this invention is to provide a girder-rail of certain form, and a chair therefor, of castiron or other suitable metal, for securing said rail in place by the interlocking of a hooked lug ,on the chair with the filleted web of the rail, the chair and rail secured together by means of a key or wedge, discarding bolts or other similar faste'nings.

The invention will first be described in detail, and then particularly set forth in the illustrates the chair in end elevation, showing the girder-rail keyed in place therein, the rail andkey being delineated in cross section. Fig. 2 shows in perspective the chair with rail detached. Fig. 3 shows in plan detached the wedge or key enlarged for locking the chair and rail together, the seat in the chair being conformed to the same taper as that given the key. The metal of one side of the chair is shown in horizontal section enlarged, taken at the dotted line 00 of Fig. 1.

In said figures the several parts are indi cated by letters of reference, as follows:

The letter A indicates the chair, B the rail, and K the key or wedge. The rail B has a bead or fillet formed under its head at G, to which the top of the chair conforms as a bed or support. The top of the chair also has a shoulder, a, overhanging its groove G. The lower part or foot of the web ofthe rail is turned up into a curved hook or offset, 12, leaving a space between it and the shoulder a of the chair,which space forms a seat or keyway for the key K. Said keyway and key may be given any suitable taper, as seen in Fig. 3, or

both key and keyway may be tapered in each direction, so that the key will have sufficient draft, both laterally and vertically.

\Vhen entering the chair upon the web of the rail, the chair is turned over to the left, Fig. 1, until its book b is entered past the shoulder a of the chair, when by turning the chair back to the vertical and raising it up until it abuts against the head of the rail the key K may be entered into the keyway formed for it between the chair and web of the rail, as above described, and driven home. When this is done, the rail will be securely locked to the chair against both horizontal and vertical movement.

The chair may be provided with braces or webs w, as is commonly practiced with railchairs, and the flangesf of the chairs may be secured to the cross-ties of the track by spikes or otherwise through holes H in said flanges.

Having thus fully described my said improvements as of my invention, I claim 1. A girder-rail provided with a fillet or bead under its head, and a web having a filleted or curved base, substantially as and for the purposes set forth.

2. A rail-chair-provided with a groove to receive the web of a girder-rail,and formed on one side of said groove into an overhanging bed for the filleted head of the rail, and forming the top of a keyway between one side of said groove and the web of the rail for keying said chair to the rail, substantially as set forth.

3. The combination of a girder-rail, as B, having a fillet or bead under its head and a filleted or curved base, a chair, as A, provided with a groove for the web of the rail and conformed to the under side ofits head, and a key having its seat in said groove, substantially as and for the'purposes set forth.

ARTHUR J. MOXHAM.
